Epidemiological and experimental studies have demonstrated the atherogenic effects of environmental toxicant arsenic and fluoride. Inflammatory mechanism plays an important role in the pathogenesis of atherosclerosis. The aim of the present study is to determine the effect of chronic exposure to arsenic and fluoride alone or combined on inflammatory(More)
Fluoride (F) and lead (Pb) are two common environmental pollutants which are linked to the lowered intelligence, especially for children. Glutamate, a major excitatory neurotransmitter in the central nervous system, plays an important role in the process of learning and memory. However, the impact of F and Pb alone or in combination on glutamate metabolism(More)
Fluoride and lead are two common pollutants in the environment. Previous investigations have found that high fluoride exposure can increase the lead burden. In this experiment, in order to study on the molecular mechanisms of central neural system injury induced by the above two elements, differently expressed protein spots in hippocampus of male mice(More)
Titanium dioxide nanoparticles (nano-TiO2) are frequently used in cosmetics, paints, sunscreens and the like. Recent studies have demonstrated that nano-TiO2 might be deleterious for the male reproductive function. However, the effects of pubertal nano-TiO2 exposure on testosterone (T) synthesis and spermatogenesis remained to be elucidated. Here, we(More)
Both fluoride and lead can cross the blood-brain barrier and produce toxic effects on the central neural system, resulting in low learning and memory abilities, especially in children. In order to identify the proteomic pattern in the cortex of young animals, from the beginning of fertilization to the age of postnatal day 56, pregnant female mice and pups(More)
Reproductive process covers lots of procedures, including capacitation, hyperactivation, chemotaxis and the acrosome reaction. Each plays an important role in the success of fertilization. Although multiple studies have reported the toxic effects of fluoride on the male reproduction, the effect of fluoride on sperm chemotaxis is little known. This study is(More)
Axonal and dendrictic degenerations were observed in non-skeleton fluorosis as the neurological manifestations. Microtubules, composed of the assembled tubulin dimers, are the essential cytoskeleton of axon and dendron. However, the effect of fluoride (F) on microtubules status and tubulin dimer expression in central nerves system remains largely unknown.(More)
This study aimed to investigate the effects of long-term fluoride exposure on object recognition memory and mRNA expression of soluble N-ethylmaleimidesensitive fusion protein attachment protein receptors (SNARE) complex (synaptosome-associated protein of 25 kDa (SNAP-25), vesicle-associated membrane protein 2 (VAMP-2), and syntaxin 1A) in the hippocampus(More)
Fluoride (F) is an essential trace element that humans and animals ingest from water, air, and fluoride-containing products; however, excessive fluoride absorption can damage a variety of organs and tissues, including the male reproductive system. Our previous studies found that fluoride exposure lowered sperm quality and interfered with spermatogenesis;(More)
